A study on EMI shielding in aircraft: introduction, methods and significance of using electrospun nanocomposites

In recent times, the explosion of digital appliances and radio communication systems has triggered an elevated debate over electromagnetic interference (EMI) in numerous industries, including the aerospace sector. EMI can disrupt verbal exchange systems, navigation gadgets, or even crucial flight controls. This paper aims to explore the need for EMI protection in the context of discussing the techniques and packages of nanocomposites used for effective shielding. It broadly covers the introduction to EMI shielding, strategies for effective shielding, and the utilization of advanced nanocomposites for EMI mitigation in aircraft. The paper also highlights the amplifying dependence on digital devices in the current aircraft and highlights the increasing coercion of EMI that leads to the demand for strong EMI-protecting solutions. Different EMI shielding techniques based on their effectiveness in protecting sensitive digital components from electromagnetic disturbances are discussed. The use of techniques such as EMI filters, shielded cables, and Faraday cages are investigated for applicability in distinctive aerospace appliances. The emerging requirement for slender and flexible EMI shielding materials that has resulted in the development of conductive polymer nanocomposites in recent years and the use of nanocomposites with excellent EMI shielding regardless of their sustaining mechanical properties has been discussed in detail. Different methods like in-situ polymerization, solution blending, layer-by-layer assembly, and electrospinning are also discussed. In conclusion, the importance of EMI protection in ensuring the dependable and stable operation of modern aircraft and the utility of polymer nanocomposites, a promising method to deal with EMI-related challenges in making air travel more secure and greener in the digital age has been impressed upon.
